Replace demo IDs, timestamps and placeholders with your own values. For a retry, keep the same IDs, time and content. These examples do not run requests on this page.
Keep login links, codes, cookies and keys private. Do not print them in logs or share them in support requests.
Read your private draft test in its authorized workspace before its 15-minute expiry. Pending, running, unknown and confirmed target failures remain distinct.
Validate a check configuration, authorized healthy locations and selectable measurement series before creating or changing a monitor. The preview shows new and retained series, remaining account capacity and estimated checks per minute. It neither creates resources nor reserves quota. Creation checks current permissions and capacity again; measurements per day are an upper bound, not actual usage. A location outage or a disabled type does not produce an invented successful preview.
